STOVE.

SPECIFICATION forming part Of Letters Patent N10. 451,284, dated April28, 1891.

Application filed November 29, 1890. $erial No. 373,013- (No model.)

To all whom it may concern..-

Be it known that 1, JOHN WERNER, of Brooklyn, in the county of Kings andState of New York, have invented a new and Improved Stove, of which thefollowing is a full, clear, and exact description.

My invention relates to improvements in that class of stoves which areused exclusively for heating purposes. The stoves most commonly used forwarming buildings heat only by direct radiation, and a considerablequantity of the heat caused by the combustion of fuel within the stovepasses away through the stove-pipe into the chimney and is lost.

The object of my invention is to produce a stove of simple construction,by means of which substantially all the heat arising from the combustionof fuel within it may be utilized for warming a room.

To this end my invention consists in a stove having a series of pipesarranged around its inner walls, said pipes opening through the bottomand sides of the stove, and this con struction will be hereinafter fullydescribed and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of a stove embodying my invention. Fig. 2is a vertical section of the same on the line a: w of Fig. 1, and Fig. 3is a horizontal section on the line 3 y of Fig. 1.

The stove-casing A, as shown in the drawings, is cylindrical in shapeand is mounted on suitable legs, is provided with the 0rdinary dampersand doors, and the top of the casing is closed by a casting A. The shapeof the stove does not form any part of my invention, however, and incarrying out my invention any desired shape may be given to the stove.lVithiu the casing A are a series of vertical pipes B and B, which arearranged around the entire inner wall of the casing, so as to touch eachother, the pipes B being longer than the pipes B and the pipesB and Bbeing alternated. Both the pipes B and B open through the bottom of thestove, as

shown at Z), and the pipes also have angular bends 1) near the top, andthe pipes at their upper ends open through the side wallof the casing,as shown at 6 It will thus be seen that the upper port-ion of the pipeswill eX- tend through the fire-box ofthe stove and will be in contactwith the flames, so that the air in the pipes will become heated, and ashot air has a tendency to rise it will pass outward through the upperends of the pipes, being replaced by the cooler air from below, so thata constant circulation will be maintained and the stove will heat byradiation in the usual way, and also by the hot-air circulation, asdescribed, so that a large amount of heat may he obtained from acomparatively small amount of fuel.

The stove is provided with the ordinary form of grate O,whioh is mountedin a collar D, said collar being secured to the casing A and havingscallops CZ therein to enable it to fit closely upon the pipes B and B.

It will be seen that as a portion of the pipes are longer than theothers the heat will issue from different points on the sides of thestove, so that it will be more evenly diffused through the room thanwould be the case if it issued from a single point upon the stove.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent- 1. A stove consisting in an outer casing, a series ofvertical pipes of different lengths alternately arranged close togetheraround the interior of the casing and forming the fire-box, the saidpipes extending through the base at their lower ends and through theeasing at their upper ends, and a grate supported within the series ofpipes above their lower ends, substantially as set forth.

2. The combination, with a stove having a series of pipes arrangedtherein, of a collar fixed to the casing and shaped to fit the pipes,and a grate pivoted in the collar, substantially as described.

JOHN WERNER.
